Spanish in the Canary Islands

I'm learning Spanish (using Duolingo) at the moment and I am aware that there are some differences between countries. My brother lives in Tenerife and I was wondering if anyone knew how they speak Spanish there? Do they pronounce words with a lisp? Are there any common words or grammar they use differently to any where else? I assume it's closest to Spain Spanish rather than Latin American Spanish?

Any information is appreciated. Thanks.
